Is it possible to set a NF environment variable such as

NXF_PARAMS_FILE

from a Gradle test?

This is a Spock test, right? If so, I think so. There should be examples in the nextflow codebase

do you know where could I find the examples? My first try is based on this but I think I am missing something here 🤔

https://github.com/nextflow-io/nextflow/pull/3086 https://github.com/nextflow-io/nextflow/commit/009ec2568ece930a207c183b17716d4c26c0645f

thank you 🙂

You’re welcome 😄

this was very useful! But now I can’t access these params from inside my script

SCRIPT_TEXT

😞

def 'test name' () {
        given:
	def folder = Files.createTempDirectory('test')
        def YAML = '''
            foo: bar
            baz:
                qux: corge
                grault: garply
            '''.stripIndent()
        def  SCRIPT_TEXT = """
            println(params.baz)
            println(params.foo)
        """

        when:
        def file = folder.resolve('params.yaml')
	file.text = YAML
	and:
        def cmd = new CmdRun(sysEnv: [NXF_PARAMS_FILE: file.toString()])
        def params = cmd.parsedParams()
        dsl_eval(SCRIPT_TEXT)

        then:
	params.foo == "bar" 
}

This is what I have now, this test passes because

params.foo == "bar"

but I need these params available inside my script for some checks. Also tried adding something like

session.params = params

and got an error

Cannot set readonly property: params for class: test.MockSession

Someone knows how could I achieve this?

😕
